DEVICE, CHIP, AND SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2022/176897
Kind Code:
A1
Abstract:
A device (100) according to the present invention captures and senses a detected substance in a liquid specimen, the device comprising: a base material (101); a flow path (103) which is provided to one surface of the base material (101) and along which the liquid specimen is fed; and a sensing zone (110) provided to one section of the flow path (103). A gel-like pillar (105) constituted by a gel-like substance is provided to the sensing zone (110), a captured substance (107) which specifically binds to the detected substance is held in the gel-like pillar (105), and the flow path (103) is formed by a plurality of flow path forming pillars (109) or microgrooves upstream or downstream of the sensing zone (110).
